Southeast District Health Department officials should have a better idea today of the number of cases in a recent Blackfoot-area salmonella outbreak, and if all of the cases were from a common strain.

Department spokeswoman Mary Howell said four cases tested positive in a laboratory, and test results of three more potential salmonella cases are pending. Howell also said the Health Department has done extensive interviews with the victims. She said seven Health Department employees spent the majority of last week investigating the outbreak.

Health Department officials have not yet released what, if anything, the victims had in common.
